## Findings

- **warn** Annotations that disagree with the tool in `estimate_charter` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "estimate_charter" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The input addresses people (input.to): what it sends cannot be taken back.
```


## Can't be undone (3)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `estimate_charter`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
An approximate charter cost for one aircraft at the hourly rate its owner published. Call it whenever the person you are helping asks what a trip would cost, with the departure and arrival airports: the beacon works out the legs and block hours from the owner's typical block speed, positioning included when the owner bills it. When the answer says the owner set no block speed, call again with block_hours, your own estimate for the routing. Answer with its sentence. Not a quote and not binding. Answers a reason instead of a figure when the owner has not published charter terms or a rate.
```

### `request_trip`

- The name "request_trip" says "request": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- The input addresses people (input.to): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Sends a charter trip request for one aircraft to the booking contact its owner named. Call it only after the person you are helping has asked to proceed, with their own name and email. Nothing is booked or held: the requester is emailed a link, the request is delivered only once they confirm it, and the booking contact then replies to them directly. If the owner set qualification questions, the first call answers needs_answers with the questions; ask the person each one and call again with their answers in the same order.
```

### `send_buyer_inquiry`

- The name "send_buyer_inquiry" says "send": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Passes a would-be buyer's message about acquiring one aircraft to the acquisition representative its owner named. Call it only after the person you are helping has asked to contact the owner, with their own name, email and message. Nothing is offered or agreed: the buyer is emailed a link, the message is delivered only once they confirm it, and the representative then replies to them directly. If the owner set qualification questions, the first call answers needs_answers with the questions; ask the person each one and call again with their answers.
```

## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_availability`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Whether one aircraft has anything scheduled on a date, or on each day of a span of up to 14 days, read from the live schedule its owner connected. Call it when the person you are helping asks whether the aircraft is available, with the departure date and, for a return trip, the return date, and answer with its sentence. Says free or taken per day and never what is scheduled. Not a hold and not a confirmation. Answers a reason instead when the owner does not publish availability.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `get_aircraft`

- The name "get_aircraft" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
What public record says about one U.S. registration mark, plus the facts its owner cleared for release. The same document as /{mark}/facts.json: status says what the registry answered (found, not_found, invalid or unavailable), public_record is the FAA registration and the datasets that reference it, and owner_approved is present only for an aircraft whose owner opened the machine-readable channel. Case and hyphens in the mark are ignored.
```

### `search_aircraft`

- The name "search_aircraft" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The aircraft whose owners chose to be listed on Owner Connect, filtered by minimum passenger seats, base airport, aircraft type, charter signal or sales signal. Every filter is applied to the facts the owner cleared for release, so an aircraft whose owner did not publish its seat count never matches a seats filter. Returns each aircraft's owner_approved block; call get_aircraft for the public record.
```
